I am a fanatic for female shoe play, the more candid and accidental the better. Even though I'm not a big fan of dangling.
The heelpop, dipping, (and/or the combination of the two )maneuvers are the best. I love the elusive walking heelpop with flats, Sperries, or even sneakers.
I've got videos with that criteria (even though they aren't my own) I am willing to trade, too but they have to meet the requirements as mentioned above.
